Accidentally plunged back in time to Poland in the year 1231, Conrad Schwartz is determined to build up the country before the Mongol invasion that will come ten years later

Anyone wondering what sort of experience prepares one for a future as an engineer may be surprised to learn that it includes delivering newspapers. But as Henry Petroski recounts his youth in 1950s Queens, New York–a borough of handball games and inexplicably numbered streets–he winningly shows how his after-school job amounted to a prep course in practical engineering. Petroksi’s paper was The Long Island Press, whose headlines ran to COP SAVES OLD WOMAN FROM THUG and DiMAG SAYS BUMS CAN’T WIN SERIES. Folding it into a tube suitable for throwing was an exercise in post-Euclidean geometry. Maintaining a Schwinn revealed volumes about mechanics. Reading Paperboy, we also learn about the hazing rituals of its namesakes, the aesthetics of kitchen appliances, and the delicate art of penny-pitching. With gratifying reflections on these and other lessons of a bygone era–lessons about diligence, labor, and community-mindedness–Paperboy is a piece of Americana to cherish and reread.

"Look out, Junie B. Jones! Ellie the engineer is thinking, making, creating, and showing enthusiasm and brilliance with her creations!" -School Library Connection A charming, hilarious illustrated middle grade about a girl who is an engineer--no, not the kind on a train, the kind that builds things! Perfect creative, STEM-powered fun for girls who have interests in how things work. Ellie is an engineer. With a tool belt strapped over her favorite skirt (who says you can't wear a dress and have two kinds of screwdrivers handy, just in case?), she invents and builds amazing creations in her backyard workshop. Together with her best friend Kit, Ellie can make anything. As Kit's birthday nears, Ellie doesn't know what gift to make until the girls overhear Kit's mom talking about her present--the dog Kit always wanted! Ellie plans to make an amazing doghouse, but her plans grow so elaborate that she has to enlist help from the neighbor boys and crafty girls, even though the two groups don't get along. Will Ellie be able to pull off her biggest project yet, all while keeping a secret from Kit? Illustrated with Ellie's sketches and plans, and including backmatter with a fun how-to guide to tools, this is a STEM- and friendship-powered story full of fun!

865 A.D. Warring kings rule over the British Isles, but the Church rules over the kings, threatening all who oppose them with damnation. Only the dreaded Vikings of Scandinavia do not fear the priests. Shef, the bastard son of a Norse raider and a captive English lady, is torn by divided loyalties and driven by strange visions that seem to come from Odin himself. A smith and warrior, he alone dares to imagine new weapons and tactics with which to carve out a kingdom--and launch an all-out war between....The Hammer and the Cross.

From the acclaimed author of The Pencil and To Engineer Is Human, The Essential Engineer is an eye-opening exploration of the ways in which science and engineering must work together to address our world’s most pressing issues, from dealing with climate change and the prevention of natural disasters to the development of efficient automobiles and the search for renewable energy sources. While the scientist may identify problems, it falls to the engineer to solve them. It is the inherent practicality of engineering, which takes into account structural, economic, environmental, and other factors that science often does not consider, that makes engineering vital to answering our most urgent concerns. Henry Petroski takes us inside the research, development, and debates surrounding the most critical challenges of our time, exploring the feasibility of biofuels, the progress of battery-operated cars, and the question of nuclear power. He gives us an in-depth investigation of the various options for renewable energy—among them solar, wind, tidal, and ethanol—explaining the benefits and risks of each. Will windmills soon populate our landscape the way they did in previous centuries? Will synthetic trees, said to be more efficient at absorbing harmful carbon dioxide than real trees, soon dot our prairies? Will we construct a “sunshade” in outer space to protect ourselves from dangerous rays? In many cases, the technology already exists. What’s needed is not so much invention as engineering. Just as the great achievements of centuries past—the steamship, the airplane, the moon landing—once seemed beyond reach, the solutions to the twenty-first century’s problems await only a similar coordination of science and engineering. Eloquently reasoned and written, The Essential Engineer identifies and illuminates these problems—and, above all, sets out a course for putting ideas into action.

In 1996, Darius Mehri traveled to Japan to work as a computer simulation engineer within the Toyota production system. Once there, he found a corporate experience far different from what he had expected. Notes from Toyota-land, based on a diary that Mehri kept during his three years at an upper-level Toyota group company, provides a unique insider's perspective on daily work life in Japan and charts his transformation from a wide-eyed engineer eager to be part of the "Japanese Miracle" to a social critic, troubled by Japanese corporate practices. Mehri documents the sophisticated "culture of rules" and organizational structure that combine to create a profound control over workers. The work group is cynically used to encourage employees to work harder and harder, he found, and his other discoveries confirmed his doubts about the working conditions under the Japanese Miracle. For example, he learned that male employees treated their female counterparts as short-term employees, cheap labor, and potential wives. Mehri also describes a surprisingly unhealthy work environment, a high rate of injuries due to inadequate training, fast line speeds, crowded factories, racism, and lack of team support. And in conversations with his colleagues, he uncovered a culture of intimidation, subservience, and vexed relationships with many aspects of their work and surroundings. As both an engaging memoir of cross-cultural misunderstanding and a primer on Japanese business and industrial practices, Notes from Toyota-land will be a revelation to everyone who believes that Japanese business practices are an ideal against which to measure success.
